Flexegraph's Nanofluids Are Cooling Formula One and Data Center Servers

The Australian deeptech company, spun out of ANU in 2015, is selling bespoke graphene-enhanced fluids for high-performance applications.

About Flexegraph

For the engineers trying to push the limits of a Formula One car or a high-density data center, the problem often comes down to a simple, physical bottleneck: heat. Conventional coolants, typically water or glycol, can only absorb so much thermal energy before they fail. The result is throttled performance, reduced efficiency, and, in the case of electric vehicle batteries, longer charging times. It is a fundamental constraint that a small Australian company, Flexegraph, believes it can solve not with a new radiator, but with a new liquid.

Founded in 2015 as a spinout from the Australian National University (ANU), Flexegraph develops graphene-enhanced nanofluids. The core technology, based on patented work with graphene and other two-dimensional materials, involves suspending engineered nanoparticles in a base fluid to dramatically improve its thermal conductivity and heat transfer capabilities [Perplexity Sonar Pro Brief]. The company formulates these advanced fluids for specific applications, selling consumer-grade products under its Go Chiller brand on Amazon and, more significantly, developing bulk or bespoke solutions for enterprise clients in automotive, data center, and high-performance computing [Perplexity Sonar Pro Brief].

A wedge into high-performance engineering

The company's wedge is a materials science one, aiming to be a component supplier rather than a systems integrator. By focusing on the fluid itself, Flexegraph positions its product as a drop-in upgrade for existing liquid cooling loops, potentially offering a performance boost without requiring a full redesign of a customer's thermal management architecture. The fluids are reported to be non-toxic and environmentally friendly, a claim that aligns with broader industry pushes for sustainable cooling solutions [Perplexity Sonar Pro Brief].

This approach has opened doors in notoriously demanding fields. According to a report from industrial giant ABB, Flexegraph partnered with Formula One and IndyCar manufacturers for pilot testing of its nanofluid cooling technology [ABB, August 2020]. The company has also established a UK branch and a Swedish subsidiary, its largest European market as of 2018, to support user trials in motorsport and high-performance engineering and to expand into European markets [Australian Department of Foreign Affairs and Trade, June 2018] [Deepbridge Capital, September 2019].

The academic roots and commercial push

The founding team blends deep technical expertise with commercial ambition. CTO and co-founder Shannon Notley is the research academic behind the core nanomaterials development [Shannon Notley - FlexeGRAPH | LinkedIn]. CEO Michael Holland brings a focus on management and strategic business development [Michael D Holland - FlexeGRAPH | LinkedIn]. The company's leadership also includes Timothy Lam as Chief Technology Officer, responsible for technical strategy and product development [ZoomInfo]. This structure suggests a deliberate effort to bridge the gap between laboratory innovation and industrial application.

Commercial traction, while early, shows a dual-path strategy. On the consumer side, Go Chiller products are available for PC enthusiasts seeking better cooling for overclocked systems [Amazon.com]. The more strategic enterprise path involves supplying custom solutions, with the company stating it can ship coolants in concentrate or pre-mix for automotive applications and has done specific development for motorsport in both internal combustion and battery-driven performance vehicles [Flexegraph Automotive Applications - Cooling the Electrified Future].

Funding and the path to industrial scale

To fuel this push, Flexegraph secured seed funding. In September 2019, the company joined Deepbridge Capital’s Technology Growth EIS portfolio, with the investor announcing a target raise of up to £1.65 million for product development, user testing, and production equipment [Deepbridge Capital, September 2019]. A separate financing database reports a $2 million round led by Deepbridge around the same date, though the company's own announcement did not state a dollar figure [Perplexity Sonar Pro Brief]. The capital appears earmarked for moving from pilot tests to broader commercial readiness.

The market need is clear. As computing power densifies and electric vehicle adoption accelerates, thermal management is becoming a critical engineering challenge. Data centers alone represent a massive addressable market where even marginal efficiency gains translate to significant operational cost savings and sustainability benefits. Flexegraph's collaboration agreement with First Graphene to supply graphene for testing in batteries and data-center cooling underscores this focus [Perplexity Sonar Pro Brief].

The risks of a deep-tech marathon

For all its promise, Flexegraph's journey is a marathon, not a sprint, typical of hardware and materials science ventures. The risks are multifaceted and substantial.

  • The adoption curve. Enterprise sales cycles in automotive and data centers are long and relationship-driven. A successful pilot with a Formula One team is a powerful validation, but it does not guarantee a volume purchase order from a mainstream automaker or a hyperscaler. These customers have stringent qualification processes and incumbent supplier relationships.
  • Manufacturing at scale. Producing consistent, high-quality nanofluids in commercial volumes, with precise nanoparticle dispersion, is a different challenge from lab-scale synthesis. Scaling production reliably and cost-effectively is a hurdle that has tripped up many advanced materials startups.
  • The competitive landscape. While no direct competitors are named in available sources, the field of advanced thermal management is crowded with approaches, from two-phase immersion cooling to novel heat sink designs. Flexegraph must continually prove its fluid-based approach offers a superior total cost of ownership.

The company's most plausible answer to these challenges lies in its focused, application-specific strategy. By not trying to be a one-size-fits-all coolant but instead tailoring formulations for motorsport, data centers, or EV batteries, it can build deep, technical partnerships that serve as beachheads into larger markets.

What to watch in the next phase

The next twelve months will be critical for Flexegraph to transition from a promising spinout to a commercial-scale supplier. Key milestones to watch include the announcement of a first major enterprise customer beyond the pilot stage, likely in the automotive or data center sector. Given the capital-intensive nature of scaling materials production, another funding round, potentially a Series A, seems a logical next step to finance expanded manufacturing capacity and a larger commercial team.

For patients and engineers dealing with the consequences of thermal overload, the standard of care today is often a compromise. In data centers, it means spreading servers out or running chillers harder, consuming vast amounts of energy. In electric vehicles, it can mean slower charging to protect battery longevity. In high-performance computing and motorsport, it means accepting physical limits that cap innovation. Flexegraph's bet is that a smarter fluid can quietly rewrite those rules, turning a fundamental bottleneck into a lever for better performance. The company's progress from an ANU lab to the edge of the racetrack suggests it has found a compelling formulation; the harder test is whether it can now mix that into the mainstream.
